Abstract

Over time, artworks often sustain paint layer separation and air gaps within their internal structure due to storage conditions and past restoration efforts. Because of this, paint layer consolidation interventions are an essential activity for art conservators. However, it is difficult to determine the exact location and the extent of layer separation on a piece of art in a non-invasive way, and even more difficult to evaluate the success of a consolidation intervention. In this work, a fifteenth-century wood panel painting was analyzed using terahertz time-domain imaging before and after it was consolidated. Using the terahertz data, it was possible to determine the areas on the artwork in need of consolidation and aid the intervention. The analysis of the after data allowed for the control and determination of the success of the consolidation effort in a non-destructive manner.

摘要

随着时间的推移，由于存储条件和过去的修复工作，艺术品的内部结构中常常会出现颜料层分离和气隙。因此，颜料层加固干预是艺术品修复师的一项重要工作。然而，以非侵入性方式确定一件艺术品中颜料层分离的确切位置和程度很困难，评估加固干预的成功与否则更难。在这项工作中，对一幅15世纪的木板画在加固前后进行了太赫兹时域成像分析。利用太赫兹数据，可以确定艺术品上需要加固的区域并辅助干预。对加固后数据的分析能够以无损方式控制并确定加固工作的成功与否。
